Galovic(Q) def. Knittel 4-6 6-3 2-1 ret.
Such an awesome week for him coming through qualies, now on to the SF against Dustov-Przysiezny winner. No idea about the reason why Knittel retired, couldn't find it, but it's great to see Viktor again with some great serve numbers
plus the result will do wonders for his ranking. I hope he doesn't feel any pressure now, even if his journey is likely to end in the next match. Vai Vik
He says on his homepage it was because of an injury.
